Works flawlessly

Never have had a problem with this app (2FAS Auth). So nice not to be bombarded with useless ads and information within the app. Never had a problem with getting codes or using them. My phone disappeared for several hours earlier this year when my husband was in the hospital. So thankful I had this app and use it for really important information. For whatever reason, someone “found” my phone & turned it in to Security. If you want extra security on your devices, this app is a great solution!
